What's Happening Now With String Theory?

"In cosmology, string theory 'packages physical models in a way that’s easier to think about,' Silverstein said. It may take centuries to tie together all these loose strings to weave a coherent picture, but young researchers like Beem aren’t bothered a bit. His generation never thought string theory was going to solve everything. 'We’re not stuck,' he said. 'It doesn’t feel like we’re on the verge of getting it all sorted, but I know more each day than I did the day before – and so presumably we’re getting somewhere.”"
